of conversion, these fi les can be transferred to the board by a
serial portal. With an analogue procedure all texts (in the various
languages) visualized on the display can be modifi ed. This time
it is necessary to modify a text fi le in standard Unicode format.
The choice of the Unicode format is decided by the necessity to
use a batch of possible characters belonging to Latin, Common
Latin, Cyrillic and Greek. For all precedent programming and
personalization functions you will just need a PC with Windows
operative system, the software equipped with RVM72A and a
standard serial cable. For PC's with just a USB portal, standard
commercial adaptor cables USB-RS232 can be used.
Also by PC, it is possible to update the Firmware of the
microprocessor of the board, or more precisely the software for
the functioning of same developed and periodically updated by
GPE Vendors. Just for this update it is necessary to connect a
PC to the CN11 connector of the board using the appropriate
interface available as an optional.
SD CARD DATA READER INTERFACE (OPTIONAL)
An optional interface is available to the purpose of reading
machine value by commercial SD card. The usable memories can
be of different sizes as 512MB, 1GB and 2GB.
The advantages of SD card memory are:
• Very contained physical dimensions. The memory can easily be
transported.
• Boundless capability of memory. With a single SD card is
possible to store a lot of reads of all the installed machines.
• Personal Computer direct reading of acquired data fi les.
• Availability and contained cost thanks to the diffusion in the
digital photographic sector.
The data of the machine are contemporarily saved in two different
formats:
• GPE-DATA format. A fi le for every machine (with name ID_XXXXX.
txt where XXXXX is the machine number programmed in the
same one) memorizes the sequential reads in legible text format.
This format is directly importable and analyzable in commercial
programs like EXCEL.
• EVA-DTS format. A fi le for every machine memorizes a single
read in such standard format. For the reading and interpretation
a special converter program is necessary.
There are two operational modes for the reading of machine data
collection:
• Insertion of the same SD card on more machines and press key
for read command
• Daily automatic reads (at a programmed hour) on the SD card installed into the machine
These two modes can also coexist in the sense that on a SD card
(with the automatic feature enabled) it is possible to save further
reads pressing the key.
It is possible to customize the selection of readed values or
groups of values and if the partial counters will be reset at the
end of the read.
